Description

Technical Field

[0001] This utility model belongs to the field of tobacco and cigarette technology, and in particular relates to a device for crushing defective and waste cigarette cartons. Background Technology

[0002] Cigarettes, also known as paper cigarettes, cigarette packs, or cigarette rolls, are tobacco products made by rolling tobacco shreds into a strip using cigarette paper. They originated in the Americas, with Native Americans using tobacco around 3000-5000 BC. Later, they spread to Europe and gradually developed into modern cigarettes. Cigarettes are usually classified according to their raw materials and aroma. Common types include flue-cured (made from flue-cured tobacco, with a distinct flue-cured aroma), blended (a mixture of flue-cured, air-cured, and sun-cured tobacco, with a rich and harmonious aroma), flavored (with unique tobacco flavors such as mint or cream), and cigar-style. (With cigar aroma), etc. In the process of selling tobacco, expired and spoiled cigarettes that cannot be sold need to be recycled. Different parts of the cigarette need to be processed separately, such as the outer packaging of the cigarette box, the filter rod, the cigarette paper, and the tobacco. Current cigarette processing equipment cannot perform classified processing. There is no special device for processing recycled cigarettes. Usually, workers need to cut and crush them manually, which is very labor-intensive. Therefore, it is necessary to provide a device for crushing defective and waste cigarette cartons to solve the above problems. Utility Model Content

The second gear 15 and the third gear 16 are meshed, and the second motor 18 drives the rotating shaft 17 to rotate the third gear 16. This causes the second gear 15 to drive the mounting shaft 13 to rotate, which in turn drives the pulverizing blade 14 to rotate, thereby pulverizing the tobacco shreds fed into the second processing box 2. The protective cover 19 is a spherical structure. The top of the protective cover 19 has a through hole that matches the mounting shaft 13, and the back of the protective cover 19 has a through hole that matches the rotating shaft 17. One end of the four sets of mounting rods 20 installed on the outside of the protective cover 19 is fixedly connected to the upper inner side of the second processing box 2, thereby achieving the fixed installation of the protective cover 19 inside the upper part of the second processing box 2.

The side of the fixing ring 25 installed on the outside of the cylinder 24 is fixedly connected to the middle of the right side of the second processing box 2, thereby realizing the fixed installation of the cylinder 24 on the right side of the second processing box 2. The extension and retraction range of the cylinder 24 is the same as the vertical movement of the sieve plate 21. The cylinder 24 can drive the connecting plate 23 to drive the sieve plate 21 to move up and down inside the lower end of the second processing box 2, so that the tobacco scraps that fall on the sieve plate 21 after being crushed by the crushing knife 14 can be screened, so that the tobacco waste that meets the required size is concentrated at the bottom of the second processing box 2 and falls through the discharge bin 6. The staff can collect the waste by placing a packing bag on the top right side of the bottom plate 4. Preferably, the front of the second processing box 2 is designed as an open structure, with a movable door 26 installed therein.
